BENCH-VISE.

SPECIFICATION formingpart of Letters Patent No. 727,246, dated May 5, 1903. Application filed September 11,1902. SerielNo.122.951. (No model.)

at Buifalo, in the county of Erie and State'of New York, have invented certain new and useful Improvements in Bench-Vises; and I do hereby declare the following to be a full,

clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being bad to the accompanying drawings, and to figures of reference marked thereon, which form a part of this specification.

My invention relates to improvements in bench-Vises, and more particularly to that class in which provision is made for both the vertical and horizontal adjustment of the aws.

The object of my invention is to simplify and condense the operation of setting the jaws and their carrying-frame in their different planes of adjustment by the employment of a single device requiring but one manipulation to simultaneously set the jaws in their frame and the frame in its base.

To that end my invention consists in the combination, with the jaws, of a frame carrying a horizontal socket, in which the jaws are adjustable in a vertical plane, such frame being split through its lower section, a supporting-base upon which the carrying-frame is adjustable in a horizontal plane, such base having a central opening surrounded by an annular holding-flange, and hooks passing through the frame and in sliding adjustment with the holding-flange, one of such hooks crossing the split in the frame and provided with means for simultaneously tightening the horizontal socket around the jaws and the frame upon its supporting-base.

In the drawings, Figure 1 is a side elevation of my improved vise, and Fig. 2 is an end view of the innerjaw with its carryingframe and supporting-base in section.

Referring to the drawings, 1 is the inner jaw, and 2 is the outer jaw, movable to and from the inner jaw l'in any well-known manner, such construction forming no part of my invention. The shank3 of the inner jaw 1 is adapted for adjustable engagement with the cylindrical socket 4 of the carrying-frame 5, having the inclined sides 6 and 7 and the circularbottom 8. The adjustment of the jaws in the-horizontal socket is twofold, one adjustmentbeing in a vertical plane and the otherbeing an endwise adjustment in such socket. Theframe 5 is split diagonally,.as at 9, from the socket 4 to the bottom 8.

10 is the supporting-base, having the central opening 11, surrounded by the annular holding-flange 12,extending downwardly and inwardly. Around the upper face of the base 10 is the annular shoulder 13, within which rests the circular bottom 8 of the carryingframe 5.

14 is a hook in loose sliding engagement with the annular flange 12. Its shank 15 passes up through the frame 5, across the split 9, and projects out beyond the inclined side 6 and has screw-threaded engagement with the blind-nut 16, provided with the turninglever 17. Y

18 is a dead-hook in sliding engagement with the annular flange 12. Its shank 19 passes up through the frame 5 and projects beyond the inclined side 7 and has screwthreaded engagement with the ordinary nut 20 for. adjusting the hook 18 into operative engagement with the holding-flange 12. Two of these dead-hooks 18 might be employed to strengthen the sliding engagement of the carryingframe 5 upon its supporting-base 10.

It will be seen. that the jaws 1 and 2 are susceptible of adjustment to any position in a vertical plane by turning them in the horizontalsocketin the carrying-frame 5. They can also be adjusted to any position in a horizontal plane by turning the carrying-frame 5 upon its supporting-base 10, and when adj usted to the proper position they can be rigidly fiXed therein by a single manipulation of the turning-lever 17, which simultaneously sets the jaws in the carrying-frame against movement in a vertical plane and-the carrying-frame upon its supporting-base against movement in a horizontal plane.

This improved construction enables me to bring the carrying-frame in close proximity to the bench or table upon which the vise is secured, which is extremely desirable in the use of large Vises for holding very heavy work where stability and rigidity are absolutely necessary.

In lieu of the hooks in sliding engagement with the holding-flange the shanks of such hooks could be extended down to and'in engagement with a bar the ends of which are in slidingengagementwiththeholding-fiange; but I prefer the form shown instead of the modification above outlined.

In a vise, the combination with the jaws, of a frame carrying a horizontal socket in which the jaws are adjustable in a vertical plane, such frame being split through its lower section, a supporting-base upon which the carrying-frame is adjustable in a horizontal frame, such base having a central open-
